IMPROVEMENT I N WHEEL-TIGHTENERS.

Specification forming part of Letters Patent No. 73,668, dated January 21, 1868.

To all whom it may concern:

Be it known that I, ENOGH SWAIN, of Lewistown, Mifflin county, Pennsylvania, have invented a new and Improved Mode of Fastening the Tire to the Wheel of any Vehicle; and I do hereby declare that the following is a full, clear, and exact description of the coneighth of an inch in depth and width, B the felly, O a female'screw, D a cylinder, with a screw on outside, E a washer, and F a spoke of the wheel.

The spokes of the wheel are out with a shoulder, forming a tenon, over which the washer E and male screw D are placed. The female screw 0 is made with a closed end and projecting iron end, G, passing through the felly, and entering the groove 8 about oneeighth of an inch.

The mode of operation consists in turning the screw 0 with a wrench, by which the tire can be tightened or loosened in a few moments, without the necessity of removing the wheel flom the carriage; and the projection G I in the groove .9 obviates the use of bolts in securing the tire to the felly.

What I claim as my invention, and desire to secure by Letters Patent, is

The combination of the circumferential grooved tire s with the screws 0 D and spoke, constructed as described, for the purposes set forth.

ENOCH SWAIN.
